What does dis=NONE mean in an email's Authentication-Results header?
Solution 1
dis=none (disposition=none) -- means that Gmail applied "none" policy

Solution 2
Wikipedia currently explains this very well:
--
The disposition reflects the policy published actually applied to the messages, none, quarantine, or reject. Along with it, not shown in the table, DMARC provides for a policy override. Some reasons why a receiver can apply a policy different from the one requested are already provided for by the specification:
- forwarded: while keeping the same bounce address, usually doesn't break DKIM,
- sampled out: because a sender can choose to only apply the policy to a percentage of messages only,
- trusted forwarder: the message arrived from a locally known source
- mailing list: the receiver heuristically determined that the message arrived from a mailing list,
- local policy: receivers are obviously free to apply the policy they like, it is just cool to let senders know,
- other: if none of the above applies, a comment field allows to say more.

The following is from an email I received recently:
Authentication-Results: mx.google.com; spf=neutral; dkim=pass [email protected]; dmarc=pass (p=REJECT dis=NONE) header.from=yahoo.com
I've been reading about SPF, DKIM, and DMARC, but I haven't found any explanation of what dis=NONE means. "dis" isn't listed in the DMARC tag registry, so where is it defined and what does it mean?

sebix almost 9 yearsAnother possible value is
QUARANTINE
and the FAQ mentionsdisposition
, so it could be the "action" to be performed. However, found no reliable evidence.

Admin almost 2 yearsIt seems that
dis=none
logically meansresult=accepted
but it's just spelled weird.
